FIbers - Weaving Yarn for Filtration Applications - Accordion Pane - FAQs - Support Scrims - US

Paragraphs

Needle-felting processes can abrade and weaken supporting scrim fibers, and yet it is the supporting scrim that contributes most to the felt's strength. The unique structure of GORE RASTEX Fibers Weaving Yarn makes it stronger and able to retain more strength after felting than other PTFE fibers. The result is stronger felts. Manufacturers can even use a looser scrim weave or smaller fiber to attain the same strength compared to other PTFE fibers, especially when GORE RASTEX Fibers Weaving Yarn is used.

What happens to supporting scrims during felt manufacturing?

FIbers - Weaving Yarn for Filtration Applications - Accordion Pane - FAQs - Shrinkage - US

Paragraphs

Manufacturers must compensate for weaving yarns that will shrink excessively during processing or in the eventual application. This process is time consuming and unpredictable, resulting in products that do not meet specifications. GORE RASTEX Fibers Weaving Yarn shrinks less at high temperatures, so filter media are more dimensionally stable, providing higher processing yields and more consistent felts and fabrics. End users will appreciate the dimensional stability because their bags and cartridges will last longer.

Why is shrinkage important?

FIbers - Weaving Yarn for Filtration Applications - Accordion Pane - FAQs - Operating Temperature - US

Paragraphs

Not all PTFE yarns perform the same as the temperature rises. Shrinkage, elongation and tenacity change as the operating temperature increases. These factors are critical for performance of filter bags and cartridges. The high tenacity available in GORE RASTEX Fibers Weaving Yarn means scrims will be stronger at operating temperatures compared to other PTFE yarns. At elevated temperatures, Gore's higher tenacity yarns also maintain more of their strength to resist the mechanical damage from high elongation forces more than other PTFE yarns. GORE RASTEX Fibers Weaving Yarns shrink less at high temperatures, so filter media are more dimensionally stable, providing higher processing yields and more consistent felts and fabrics.
